In the group create object you have 'resources'.
Can you explain what you expect in there? I thought we talked at
summit about have a unit of scaling as a nested stack.
The thinking here was:
- this makes the new config stuff easier to scale (config get applied
per scaling stack)
- you can potentially place notification resources in the scaling
stack (think marconi message resource - on-create it sends a
- no need for a launchconfig
- you can place a LoadbalancerMember resource in the scaling stack
that triggers the loadbalancer to add/remove it from the lb.
I guess what I am saying is I'd expect an api to a nested stack.
